Treatment of a Rare Case of Longitudinal Forearm Instability: A Case Report.

Case: A 41-year old man fell from height sustaining displaced radial shaft and ulnar styloid fractures underwent open reduction internal fixation of the radius with early recognition of a radiocapitellar dislocation and longitudinal forearm instability in the early postoperative period. Revision surgery was performed 13 days postoperatively involving annular ligament reconstruction, elbow spanning external fixation, and distal radioulnar joint stabilization. Favorable functional and radiographic outcomes are shown at 1-year follow-up.

Patient-Level Value Analysis in Total Hip Arthroplasty: Optimizing the Value of Care Delivery.

Background: Value is defined as the ratio of patient outcomes to the cost of care. One method to assess value is through patient-level value analysis (PLVA). To our knowledge, this tool has not previously been implemented in the setting of total hip arthroplasty (THA).

Frustrations in Providing Orthopaedic Trauma Care: An OTA Member Survey Study.

Objectives: To determine sources of frustration for surgeons and how they might affect job satisfaction within the orthopaedic trauma community.

Methods: A 25-question survey regarding potential common causes of frustration, operating room (OR) utilization, and career satisfaction was electronically distributed to the Orthopaedic Trauma Association (OTA) membership.

Results: Four hundred seventy-one surgeons participated in the survey (response rate 27.

Psoas Sarcopaenia Outcomes in Elderly Patients After Acute Lower Gastrointestinal Bleeding.

Introduction Sarcopaenia has been examined as a predictor of frailty in surgical patients and may predict mortality. The hypothesis of this study is that sarcopaenia is associated with an increased risk of death following an episode of acute lower gastrointestinal bleeding (ALGB). Methods This study included patients admitted with ALGB between January 2017 and June 2022, who underwent cross-sectional imaging (CSI).

Bioinspired designer DNA NanoGripper for virus sensing and potential inhibition.

DNA has shown great biocompatibility, programmable mechanical properties, and precise structural addressability at the nanometer scale, rendering it a material for constructing versatile nanorobots for biomedical applications. Here, we present the design principle, synthesis, and characterization of a DNA nanorobotic hand, called DNA NanoGripper, that contains a palm and four bendable fingers as inspired by naturally evolved human hands, bird claws, and bacteriophages. Each NanoGripper finger consists of three phalanges connected by three rotatable joints that are bendable in response to the binding of other entities.
